SPECIFICATION forming part of Letters Patent No. 253,899, dated February 21, 1882.

Application filed J nne 13, 1881. (No model.)

' To all whom it may concern:

Be it known that I, ARTEMAS B. UPHAM, of

Peoria, in the countyof Peoria, in the Staterefer to like parts, and in which-- Figure 1 represents a side elevation of chair in its most erect position; Fig. 2, a side elevation of the same folded up; Fig. 3, a view of complete chair inclined to its greatest extent;

Figs. 4 and 5, end and side views of adjusting attachments.

The object of this invention is the construction of a chair which shall be capable of being adjusted to any convenient angle of inclination, and shall also be capable of being folded up to the smallest possible compass for transportation or storage.

I will describe the formation and operation of only one side of the chair, as both sides are 2 5 of course just alike.

The main part A A of the chair forms from its upper extremity down to Z the side bar of r the back of the chair, and the lower part, A,

forms one of the front legs of the chair. The

sidebar, D, of the chair-seat is supported near its rear end by the bolt, screw, or rivet S, pivoting it to the main piece A A, and near its other end by the bolt, screw, or rivet T, pivoting it to the brace C, said brace 0 being held 3 5 up by being pivoted to the arm-piece E by the bolt or rivet O. This arm-piece E is in its turn supported by means of the prolongation B of the rear leg, B, and also by having oneend pivoted at P to the main piece A A. This leg B is pivoted to the said main piece A A by the screw, bolt, or rivet B. To enable the rear leg, B, to be adjusted to different angles and so alter the inclination of the chair, the end B of said leg B is adapted to be secured to sev eral different points, as desired, on the under side of the armpiece E. The device 1 hare adopted for this purpose consists of a metal bar, F, of a double T (I) shape in cross-sea tion, the upper cross being simply for the pur- 5o pose of attaching it to the under side of the arm-piece E. The lower cross part or rim is fitted to slide easily back and forth in the inverted-T-shaped notch made in the attachment H, secured to the end B of the extended leg B. Into a hole running through this attachment H, at right angles to the direction of the notch just mentioned, the hook-lever J is made to play easily, it being pivoted just below said hole and furnished with a spring to throw it in, after the pressure of the finger against its other end has drawn it out. The bar F has several holes, f f f f, large enough for the reception of said hook-lever J. By means of these three parts F, H, and J the end B of the leg B can be retained at as many points along the arm-piece E as there are holes f.

As it is desirable to have the seat (represented by its side bar, D,) at as much of an incline as possible consistent with its construction when the chair is tilted back to its lowest inclination, the distance between the the pivots 1? and 0, so that as the arm-piece E is lowered at 0 about P as a pivot the point T will traverse the same distance as the point 0, but the radius 8 T of the former being longer than the radius P O of the latter, the 'angular downward movement of the seat D will be less than that of the arm-piece E. The relative lengths of the distances P O and S T, to enable this chair to fold up, must be con trolled by the formula 1? 0+0 T=P S+S T.

chair at such a height above the seat D as to support the small of the back of the person sitting thereon.

The mode of operation of my adjustable folding chair is as follows: Taking the chair as it is shown in Fig. 1, and supposingit is desired to tip it back to a greater degree of inclination, we press the finger against the lower end of the hook-lever J till it is released from the hole fin the bar F. The weight of the chair then makes the leg B slide away from the leg A, and therefore the end B toward the front end of the arm-piece E. When the desired in clination of the chair is reached the hook-lever -J is released from the pressure of the finger and by its spring snaps into the first hole f it comes to.

the leg B is carried backward till the T-shaped notch in the attachment H is released from the pivots S and T is made longer than between- I place the cross-piece Z of the back of the To fold this chair up, the end B of I00 bar F, when the legB is folded up against the part at P of the arm-piece E, and the seat D, brace O, and arm-piece E are folded down against the leg A.

In testimony that I claim the foregoinginvention I have hereunto set my hand this 6th ARTEMAS B. UPHAM. Witnesses H. W. WELLS, RIOHD. A. GoLDsBROUGH.
